Abstract (en)
A video surveillance system is disclosed in which modulated signals from a plurality of video cameras are multiplexed onto a signal path capable of carrying for example up to 36 video channels. One or more such communication paths are provided to a signal splitter which provides the paths to one or more video screens and tuners. The tuners are operated under computer control so as to sequence the display of information from the different video cameras. Advantageously, means are also provided for recording the video display on a VCR when a display includes matters of interest. The computer is also responsive to alarm inputs to display on one or more screens the signals from video cameras in the area adjacent the alarm.
